'Els 4 Gats' (The Four Cats), is a café in Barcelona opened in June 1897. Active until 1903, Els Quatre Gats became one of the main centers of Modernisme in Barcelona. The artist Ramon Casas i Carbó largely financed this bar on the ground floor of Casa Martí (1896), a building by the architect Josep Puig i Cadafalch in Carrer Montsió near the center of Barcelona.
